BURR A. KENNEDY, OF CHICAGO, ILLINOIS.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 434,021, dated August 12, 1890-.

Application filed May 12, 1890. Serial No. 351,680. (No model.)

To all whom it may concern.-

Be it known that I, BURR A. KENNEDY, of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Harvesters, of which the following is a full description, reference being had to the accompanyin gdrawin gs, in which Figure 1 is a rear end view of so much of the harvesting-machine as is necessary to show my invention. Fig. 2 is a stubble-side sectional view of same, as if out on the lines Figs. 3 and 4 are details.

In the drawings, A is the main supportingwheel; B, the grain-receiving platform; C and C, the elevating devices, preferably constructed of two canvases, one above the other; but any form of elevator may be used in'lieu thereof. These elevating devices are so supported as to be independent of each other at the rear end in so far as to permit any grain which is carried by them to project rearward beyond them, my object being to make an elevator that may carry up grain or corn.

The lowermost of the two elevators is sup ported upon the frame D, which in turn is sustained by the post D, the frame and the post each being footed onto the lower framework of the machine in the usual manner. At the forward end of the machine is preferably a metallic plate E and a post E. These form a support for the forward end of the elevating devices.

In order to support the rear end of the uppermost elevating device, or in case a simpler grain-cover is used (as upon the old Marsh harvester) to support the latter, I provide a U-shaped support F, so clamped to the lower portions of the main harvester-frame at F as to be properly sustained, and extend it rearward and then curve it upward and forward and allow it to pass, preferably, underneath the seat-plank G. The seat-plank is securedto E at its forward end, and is provided with clamps G and G which secure it to the seat-board. As it is not always necessary to have the support F extend as far rearward as shown, I so adapt it that it may'telescope, so to speak, in its supports. In cutting corn it would be in the position shown in full lines of Fig. 2, while in cutting grain it might be in the position shown by dotted lines in Fig. 2.

In Figs. 3 and 4 I showthe structure of the clamping devices F. A set-screw F extends through the bracket which is bolted to the rear platform-sill, and in this is a gas-pipe H, bolted at the front in the bracket F Into this gas-pipe the U-shaped bar F may slide, and by loosening the set-screw F and the clamps G and G it may be slid to any position required.

In order to prevent the support F from moving sidewise, I provide a brace I, which I preferably make in two parts, as I and I, and connect them by any suitable device, as 1 This brace is connected to the post D, and it will be readily understood that its length may be varied to correspond with the various positions to which the support F is adjusted. I do not limit myself to the use of this brace, because the parts can be made so stiff as to not require it, but would necessarily be somewhat heavier. I therefore show it. J is an extension of the plane of the lower elevator, but constructed of boards or sheetiron, provided for the purposebf guiding long grain or cornstalks in their passage upward.

I have shown II to be a tube. This is not essential, as itmay be a flat bar and the bar F clamped to it precisely as the said bar is clamped to the board G; but I prefer the pipe.

I have shown special means for adjusting the length of the brace composed of the parts I and I-namely, the clamp I but I do not limit myself to such construction, nor do I limit myself to a brace the length of which can be varied, because the same purpose would be served if braces of various lengths were used, and Ishould consider them equivalents.

I do not claim supporting the seat-board upon any U-shaped support, as F, and connecting thereto the upper elevator-frame for the purpose of support, as this construction,

as well some features which I have shown but not described, is the invention of John F. Steward.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. The combination of the elevators C and C and the adjustable support F, substantially as described.

2. The combination of the seat-board support- G, the main frame, and the adjustable support F, substantially as described.

3. The combination of the main frame, the seat-support G, and the elevators O and C, and adjustable support F, substantially as 2 described.

4. The combination of the main platform having the pipe or its equivalent H, the support G, for sustaining the elevating-canvas O, and the support F, adapted to telescope rela- V tive thereto in its adjustment and be held,-

substantialy as described.

5. In a harvester, the combination of the
